“…It reduces blood flow to all splanchnic organs, thereby leading to a decrease in portal venous inflow and to a decrease in portal pressure. The clinical usefulness of vasopressin is limited by its multiple side effects, which are related to its potent vasoconstrictive properties, including cardiac and peripheral ischemia, arrhythmias, hypertension, and bowel ischemia (60). Although its efficacy and safety are significantly improved by the addition of nitrates (50), side effects of combination therapy are still higher than those associated with terlipressin, somatostatin, or somatostatin analogues (35) and, therefore, it can only be used continuously at the highest effective dose for a maximum of 24 hours to minimize the development of side effects.…”
